Linux History and GNU

Linus Torvalds,a student at the University of Helsinki started developing Linux to create a system similar to MINIX, a UNIX operating system. In 1991 he released version 0.02; Version 1.0 of the Linux kernel, the core of the operating system, was released in 1994. About the same time, American software developer Richard Stallman and the FSF made efforts to create an open-source UNIX-like operating system called GNU. In contrast to Torvalds, Stallman and the FSF started by creating utilities for the operating system first. These utilities were then added to the Linux kernel to create a complete system called GNU/Linux, or, less precisely, just Linux.

Linux grew throughout the 1990s because of the efforts of hobbyist developers. Although Linux is not as user-friendly as the popular Microsoft Windows and Mac OS operating systems, it is an efficient and reliable system that rarely crashes. Combined with Apache, an open-source Web server, Linux accounts for more than a third of all servers used on the Internet. Because it is open source, and thus modifiable for different uses, Linux is popular for systems as diverse as cellular telephones and supercomputers. The addition of user-friendly desktop environments, office suites, Web browsers, and even games helped to increase Linux’s popularity and make it more suitable for home and office desktops. New distributions (packages of Linux software) were created throughout the 1990s. Some of the more well-known distributions include Ubuntu,Red Hat, Debian, Mint etc.Linux adoption grew among businesses and governments in the 1990s and 2000s. In the English-speaking world at least, Ubuntu and its derivatives became a relatively popular group of Linux distributions.

The name “GNU” is a recursive acronym for “GNU's Not Unix!”;

GNU was launched by Richard Stallman in 1983, as an operating system which would be put together by people working together for the freedom of all software users to control their computing. The primary and continuing goal of GNU is to offer a Unix-compatible system that would be 100% free software. Not 95% free, not 99.5%, but 100%. Technically, GNU is like Unix. But unlike Unix, GNU gives its users freedom.
Completely free system distributions (“distros”) meeting this goal are available today.Thousands of people have joined in to make GNU the success it is today, and there are many ways to contribute, both technical and non-technical.


GNU has been supported in several ways by the Free Software Foundation, the nonprofit organization also founded by Richard Stallman to advocate free software ideals. Among other things, the FSF accepts copyright assignments and disclaimers, so it can act in court on behalf of GNU programs. (To be clear, contributing a program to GNU does not require transferring copyright to the FSF. If you do assign copyright, the FSF will enforce the GPL for the program if someone violates it; if you keep the copyright, enforcement will be up to you.)
The ultimate goal is to provide free software to do all of the jobs computer users want to do—and thus make proprietary software a thing of the past.
“The Free Software Foundation (FSF) is a nonprofit organization with a worldwide mission to promote computer user freedom and defend the rights of all software users.”

Introduction to Data Structures

Visit My Data Structure Blog for Programs... It is important for every Computer Science student to understand the concept of Information and how it is organized or how it can be utilized. If we arrange some data in an appropriate sequence, then it forms a Structure and gives us a meaning. This meaning is called Information . A data structure is a particular way of storing and organizing data in a computer so that it can be used efficiently. Data may be organized in many different ways. The logical model of a particular organization of data in a computer is called data structure. The choice of the model based on two considerations. It should be reflect the data in the real world. It should be simple that one can effectively process the data when necessary. E.g. Array, linked list, stack, queue, tree, graph Data structure can be classified into two: Linear: A data structure is said to be linear if its elements form a sequence E.g. Array, linked list, stack, queue Non-Linear: A dat

Basic Linux Commands For Beginner's

Basic Linux Commands for Beginners Linux is an Operating System’s Kernel. You might have heard of UNIX. Well, Linux is a UNIX clone. But it was actually created by Linus Torvalds from Scratch. Linux is free and open-source, that means that you can simply change anything in Linux and redistribute it in your own name! There are several Linux Distributions, commonly called “distros”. A few of them are: Mint Ubuntu Linux Red Hat Enterprise Linux Debian Fedora Kali Linux is Mainly used in Servers. About 90% of the Internet is powered by Linux Servers. This is because Linux is fast, secure, and free! The main problem of using Windows Servers are their cost. This is solved by using Linux Servers. Forgot to mention, the OS that runs in about 80% of the Smartphones in the World, Android, is also made from the Linux Kernel. Yes, Linux is amazing! A simple example of its security is that most of the viruses in the world run on Windows, but not on Linux
